JK-1200 Bottom Loading Furnace:

1. High temperature bottom loading furnace is capable of operating at temperatures up to 1200C in air.
2. The furnace utilizes Fe/Cr/Al Alloy resistance wire positioned on three sides of the internal chamber.
3. The furnace utilizes an energy efficient insulation package consisting of graded ceramic-fiber, high temperature insulation. It is an ideal tool for materials annealing and sintering. 


1. Bottom Loading Furnace Features:

a. Controlling Accuracy: +/-1C 
b. Temperature uniformity: +/-1C (according to the heating chamber size)
c. Control system: Micro-computer controlled, Easy to operate, programmable, automatic heating up, automatic heat preservation, automatic cooling.
d. Working temperature: 1100C
e. Stainless steel Metallic flanges sealing (Double rubber ring)
f. Outside temperature of the furnace is close to room temperature
g. Double-circuit protection
h. Super refractory material, Excellent thermally resistant, High temperature resistant, Thermal shock resistant.

2. Bottom Loading Furnace Construction:

a. High purity ceramic fiber insulation (energy saving 40% and weight lighter about 30% than old furnace).
b. Double layers steel casing with fan cooling, to ensure the surface of furnace below 50°C.
c. Lifting bottom controlled by electric, freely lift or down.
d. Up and down limited switch, double safety for bottom moving.

3. Bottom Loading Furnace Application:

a. Gravimetric Analysis;
b. Sintering or Roasting or Forging or Calcining;
c. Quantitative Analysis;
d. Heat Treating or Preheating;
e. Quenching or Hardening or Austempering;
f. Annealing or Tempering or Normalizing;
g. Stress Relieving;
h. Temperature Measurement.

4. Bottom Loading Furnace Warranty:

JK Bottom Loading Furnaces are warranted to be free from defects in materials or workmanship for 2 years from the date of purchase. Within this period, across International will, at its sole options, replace any components that fail in normal use. Such replacement will be made at no charge to the customer for parts, provided that the customer shall be responsible for any transportation cost.
